That was the identified test case from the issued referenced in #3609.  I didn't write any of that nor participate in that issue. I just determined that my fix below for another issue fixed that issue as well and this is the test case to prove it.

I think the reason this passes with my fix, is that previously the `resample()` code-path hard-coded a day (`'D'`) freq and this sample case used 'T'.

I'll add the hard-coded expected result just to complete this.
